Application filed November 22, 1913. Serial N0. 802,512.

To all whom, it may concern,

Be it. known that I, Joi-IN Mann TOBIAS, a citizen of the United States of America, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Gas HeatingStoves, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a gas heating stove, and has for its object to provide a stove of such class, in a manner as hereinafter set forth, whereby when in operation 'it will be free of obnoxious fumes.

Further objects of the invention are to a provide a gas heating stove, which is simple in its construction and arrangement,strong,

durable, efficient in its use, insuring perfect combustion, having the burner elements thereof substantially indestructible and maintained 1n perfect alinement, compact, readily assembled, sightly in appearance and comparatively inexpens ve to manufacture.

With the foregoing and other objects ini view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

' In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a longitudinal sectional View oia gas heating stove in accordance with this invention, Fig. 2 is a cross sectional view of the same, and Fig. 3 is a-sectional plan of a burner. I

Referring to the drawings in detail, 1 and 5 denote a pair of end plates provided with openings 6, 7, and further having openings, 8, 9, for supporting "a longitudinally extending gas supply pipe 10, the latter being capped at one'end as at 11, whereby the said end is closed and having attached to its other end a cut-oft" 12, which is adapted to communicate with a gas feed pipe (not shown). The pipe 10 projects from each of the end plates 4 and 5.

The reference character 13 denotes the casing of the stove and which is positioned [between the end plates and is substantially semi-oval in vertical section. The casing 13 wet less height than the height of the casing 13 are overlapped. The casing 13 abuts against the inner faces of the end of thin metallic material, which is perforated throughout, the perforations, by way are indicated at 15. The ends of the sheet of material from which the casing 13 is construeted are formed with inwardly extendn'g, flanges 16, thereby partia ly closing the ottom of the casing. a

The end plates 4, 5, are cut away at their lower ends to provide supporting legs 17 (and the said end plates are coupled together through the medium of a combinedsupporting and coupling bar 18, which is concave jin cross section and has the longitudinal edges thereof spaced from the inner faces of the sides of the casing 13 The bar 18 is formed with depending fia ges 19, which are fixedly secured to the inner faces ofthe end plates 4;, 5, through the medium of the holdfast devices 20.- The bar 18 is furthermore provided, centrally thereof, with a longitudinal row of openings 21., which are equally spaced with respect to each other, the function thereof will be presently referred to. i

The bar 18 is positioned between the center and top of the casing 13 dividing the chamber formed by the easing into an upper and a lowerportion and as the longitudinal edges of the bar 18 are spaced from the inner faces of the sides of the casing 13, passages 22, 23, are provided which establish communication between-the upper and lower portion of the casing 13.

Supported by the pipe 10 and extending into the easing13, at the bottom of the lat ter, is a longitudinally disposedalining bar 24 provided with equally spaced openings 25, for a purpose to be presently referred to,

disposed ends 26,27terminatingincollars28, which-are mounted upon the p pe'10 and maintained in position through the medium of set screws 29 carriedby said collarsand capable of abutting against the. pipe 10 when adjusted. By such an arrangement. the

end plates 4, 5, and these latter are flanged inwardly as at 14, whereby the ends of the of example being illustrated as rectangular,

plates 4-, 5, and is formed of a single sheet and further having depending angularly the top which is indicated but it is obvious that the number can be increased or diminished. The burners are disposed vertically and positioned equidistant with respect to each other. Each of the burners is indicated by the reference character 30, has the intermediate part of the body portion thereof cylindrical throughout and formed with vertical rows of openings 32, by the reference, character 31- ro'unded. The bottom of the body portion-'ofgthe burner 30 is funnelshaped in contbur 'as'indicated by the reference character. 33 and terminates in a cylindrical mixing tube 34, which is of materially less diameter than the body portion of the burner and is imperforate throughout.

The body p'tirtion of the burner 30, in proximity to the bottom 33 thereof is formed with a pair of rectangular openings 35, which oppose each other and projecting from the top of each opening 35 is a 1aterally extending inclined lug 36. The lugs 36 are disposed in opposite directions with re spect to each other and when a plurality of burners are employed in the stove, the lugs of the opposing sides of the burners abut as clearly illustrated in Fig. 1, and form what may be termed a brace for the burner body. The openings 35 are employed primarily for the purpose of the escape of gas or flame from one burner body to ignite the gas in the other burner body. I

The openings 21 in thebar 18 are employed for the passage of the upper ends of the burners 30-andth'e openings 25 are utilized forvthe passage of the mixing tubes 34. B such an arrangement, the upper ends o the burners are retained in spaced relation by the bar 18 while the mixing tubes 34 are maintained in spaced relation by the bar 24. The mixing tubes 34; are provided with laterally extending supporting lugs 37, which engage the bar 24 and support the burners 30.

To prevent shifting of the burners when mounted in the bars 18, 24, the body portion of each burner has formed on each sidea vertically dis osed rib 38, which is seated in a notch 39 ormed in the wall of the opening '21. By such an arrangement rot-ative movement of the burners is prevented.

Arranged in alinement with the center of the mixing tube 34, as well as being spaced therefromare outlet nipples 40 carried b the supply pipe 1-0. Arranged in the'bottom 33 of each burner 30 is a Wire sieve 41, whichconstitutes a filler and provides means to arrest the entrance of any foreign substances to the burner 30, and furthermore spreads the mixture of gas and air.
